Sibilla was described as a man who was interested in everything, and neighbors said he did not let age or his walker get in the way of living a full life.

"When I heard about the mugging and the attack, it was like, this guy, if you pushed him with one finger he would have fallen down," neighbor Christina Britton Conroy said at the time. "He was so frail. So why would anybody needed to beat him up?"

Conroy served with Sibilla in a church group that performs at local senior centers. She said though he used a walker, it never stopped him from participating or from offering help when and where needed.

"Joe was the kind of guy you want everybody in the world to be," she said.
